Dennis, widely known as the young hero Clockblocker, is a member of the Brockton Bay Wards.


Dennis likes to joke about everything, deliberately choosing an offensive cape-name because he found it funny.[3] Given his father having a life threatening illness for much of his life, he may have used this as a coping mechanism.

Clockblocker has had a tendency to be willing to work alongside the "villains", going so far as showing some kind of fondness for Skitter. However, he never crossed the line into being a villain. He does help Skitter cut Echidna in half using a frozen piece of spider silk.

Clockblocker is observant and understands the social and political implications the revelations of the The Triumvirate's actions on the Protectorate as well as the utter wreckage it would have on the team dynamic of the Protectorate teams.[4]


Clockblocker has become jaded by his experiences. And was far more sarcastic and acerbic than he used to be.


Vista Edit

Vista was his teammate and friend on the Wards. The two shared a useful team dynamic and were able to use their powers effectively together.

Appearance & Equipment Edit

Dennis is Caucasian with red hair, blue eyes and about average height.

Clockblocker wore a skintight white costume,[5] with panels of glossy white armoring placed strategically to not inhibit his movement. It covered every inch of his skin. The armor had grey clocks inscribed on it; the ones at his shoulder, the center of his chest, and the backs of his hands - the places the armor was broadest - had hands that moved at different speeds[6] using digital displays.[7]

His helmet was a faceless, smooth expanse of white.[5][6] By the time he was a member of the Protectorate, his mask featured an animated clock over the face.[7]

His costume included a utility belt, which included, among other things, flashbangs[8] and paper. Which he could freeze to create barriers or "steps" in midair.[9]

Later in his career, he would incorporate more equipment into his suit as he found more creative ways to use his powers. Mainly a gauntlet with propelled finger projectiles,[10] and a rapidly deployable tent built into his backpack.[11]

Abilities and PowersEdit

Clockblocker could "tag" nearly anything, freezing it in time.[2] His powers remained comparatively static throughout the story-line. This power could affect living creatures,[6] including humans, as well as inanimate objects.[9][12]

Targets were stuck in the air, immobile, but weren't harmed.[6] They were immune to conventional attacks.[12] He described the effect as being "inviolable", according to "the doctors", and claimed that he would sooner expect Siberian to "fold the universe in half" than break something he froze.[13] Thin objects could be extremely sharp, threatening enemies who moved into them.[9][12]

Clockblocker could freeze something within a fraction of a second of it making contact,[6] whether it be his hands, feet,[14] or any part of his body. He could freeze only the bugs that were in contact with a section of his body, or everything in contact with him at once.[6] He was able to tag Leviathan without being injured, though it did cause him to almost drown in the water he was in.

Clockblocker couldn't disable the effects of his power.[6] Objects remained frozen for a period between 30 seconds and 10 minutes, with no control over the time limit.

His power worked through interconnected objects, but it had a limited range. Like many parahumans, his power's strength varied based on his mental state. He was just barely able to push it through the thread binding Echidna and Ignis Fatuus, noting that his power must have been "working at peak efficiency" at the time.[15]



Dennis triggered when he was 15. While donating bone marrow to his father to help with his condition, the stress of the situation gave him his powers.[1] The needle that was about to be inserted into his bones when extracting marrow was what shaped his powers into a striker ability,[16] being able to pause time as his fathers' was rapidly running out.[17]

Story StartEdit

Got into a compromising position during the Battle at the Bank when he panicked and froze some of Skitter's swarm, accidentally pinning himself in place.

He and Vista were able to stop Bakuda's final bomb.[18]


Dennis' father was dying of cancer, previous medical treatments being ineffective, but he asked Panacea and Glory Girl for a favor in curing his father of cancer, which they gave him.[19]

Post-Slaughterhouse NineEdit

Was a major part of Piggot's plan to take out the Nine.

Was later instrumental again in turning the tide in the fight against Echidna


Was involved in the revelations concerning Skitters identity at Arcadia High.

Gold MorningEdit

Clockblocker died during the battle against Scion before Glaistig Uaine claimed him, using his abilities to fight the mad Worm.

Valkyrie speculates that she may be able to resurrect her ghosts in some form by merging them with Nilbog's creations.[20] A figure that may be Clockblocker, a young man with red hair wearing a white bodysuit, later appears alongside her.[21][22]

Trivia Edit

  • The movable clock faces on Clockblockers costume are not tinkertech. Such screens exist in reality.

  2. 2.0 2.1 Clockblocker and Vista are your best assets. Clockblocker is a Striker 7 with touch-based time-stopping. - Excerpt from Sentinel 9.1
  3. say clockblocker ten times fast
  4. He wasn’t wrong. We were suffering losses, and we hadn’t achieved anything. Echidna was as strong as she’d ever been, stronger than she’d been at the outset of the fight, and she kept on acquiring clones that cost more than we could afford to put down. Alexandria and Eidolon were only the tips of the iceberg.

    “It’s a big hit to morale, but-”

    “No,” Clockblocker cut me off. “We lost. Not this fight. Maybe we can still win it, won’t deny it’s possible, with Scion maybe showing up. But the big picture? There’s no coming back from this. Without the Protectorate, without all the work that it does to organize heroes around the world, there’s no getting everyone working together. The amount of anger? The suspicion, wondering if a teammate took the formula or not? How can we go up against the next Endbringer that shows up?” - Excerpt from Scourge 19.6
  5. 5.0 5.1 Clockblocker – A member of the Brockton Bay Wards, wears a white skintight costume with body armor. Has flat, featureless pane over his face to serve as a mask and clock faces studding the armor. Can freeze something in time for an indeterminate period on touching it. - Worm Cast Page

  7. 7.0 7.1 I glanced at Clockblocker, but he appeared unfazed. Not that I could really tell. His armor still had animated clock faces digitally displayed on the open spaces, and there was one in the middle of his face. - Excerpt from Sting 26.3
  8. Aegis [wearing Clockblocker's costume] didn't try to run this time. He stood his ground and reached for his utility belt. He retrieved something that looked like a miniature fire extinguisher.

    Then he pulled the pin. - Agitation 3.10

  10. Clockblocker used his glove, and the fingertips shot out with explosive force, with what looked like gleaming white fishing line stretching between the digits and the glove. The tips punched into a wall. A fence of thin lines, not much different from my spider silk.

    Dragon put her hand on the glove, and the tips retracted just as fast. My bugs could hear her speaking. “…’ll hurt … civilians.” - Excerpt from Chrysalis 20.5
  11. Clockblocker activated the device on his back. A dome unfolded around him, almost like a tent, though more rigid.

    Rachel had already fled with her dogs. Even so, it was tight, everyone pressed together inside.

    He froze the dome.

    I regretted that I didn’t get to see the follow-up attack.

    The Thanda had a cape that was sort of in the same vein as Shuffle. A teleporter of landmasses.

    This cape didn’t need to teleport things onto solid ground. In fact, he specialized in the opposite.

    A large building was teleported into the stratosphere, where it summarily fell on the cube. I could hear the crash through the cameras the Brockton Bay Wards wore.

    Siberians down, I thought. - Excerpt from Sting 26.5

  16. This conforms. In this case it was the needle that was to go into Dennis' leg that crystalized it as a striker trigger. - Wildbow on Reddit
  17. In this case the striker component was the tool being used. The irony/theme come into play with his dad having so little time, and CB knowing that but still caving due to the pain. - Wildbow on Reddit Again
