Comparison:
Attack Potency:
- Heatblast: 20.58 Exatons
- Omni-Man: 5.5 Exaton
- Heablast holds 3.74 AP advantage
Lifting Strength:
- Heatblast: Class G
- Omni-Man: Class G
- Both are equal in this department advantage
For Heatblast he has:
Fire Manipulation: Heatblast lives called his home world which is a star called
Pyros.
HB’s heat should be comparable to the star he lives on. Which would be around 6000 Kelvin of an average Star.
This is just the surface temperature of a Star… A regular pyronites’ body (living on Pyros) temperature should be comparable to the surface temperature of a Star by virtue of how heat works in a non-isolated system.
Heatblast (Omni-Enhanced Version):
There is also the fact that this is
Omni-Enhanced Heatblast form which is having a high mobility advantage as he has Energy Jets on his back that would allow him to dominate the Arial combat as he has
Shock Rocks DNA in this form who is arguably one of the strongest Omnitrix alien,Thus allowing him to make Fire and Electricity deadly combo attacks and utilize his techniques mentioned on his page such as
Aero-Dynamic attack and
Electro-Fire Breath which he would be able to shoot at Dust Man from Dozens of Meters away while constantly moving through the air as he did by defeating hundreds of Drones that were after him in the show also when it comes to his Flight speed in his Omni-Enhanced form, He surpassed
Xlr8 who everybody knows is the fastest alien on the ground for Ben yet Omni-En HB
surpassed him. This would at the bare minimum makes him
harder to hit in such situations, Plus his
Calorific laser can slice objects in half from a distance as well as he domiants Arial combat.
Feats:
So not only is his flight faster than Base XLR8 who is the fastest alien Ben got but also he's got a ton of
Techniques list on his page as well as Omni-Enhanced combo power advantages, Omni-Enhanced Heatblast casually flies around and faces and defeats Large Size Type 1 Robots who are sky Scrapper sized.
Experience and Intelligence:
- Heatblast harmed and defeated warlord Vilgax who has conquered 10 planet and a Supergenius who co-created Omnitrix alongside Azmuth.
- Heatblast was able to harm Alien X (The strongest enemy Ben has ever faced with reality warping powers.)
- Since the user is Ben he was able to defeat Hex who is a 10,000 year old magican with vast knowledgable of dimensional portals 0:18 (who was amplified by dozens of magic books during their battle but Ben outsmarted him multiple times despite his magic amplifications).
- Ben was able to fight against Agent Six who is titled "Sixth deadliest man on the planet" yet Ben was able to hold his own against him during "Ben Gen 10" Crossover
- Here are the Ben vs Vilgax fights and he defeted 4 vs one Weatherheads robots all by himself super casually (Ben vs vilgax, Ben vs Vilgax and Weatherheads and Ben vs Anti-Vilgax who has power 10 different Anti-trix aliens absorbed). Ben is clearly able to keep up with him and robots, monsters from outerspace who are more stronger than him in one vs Multi Opponent scenarios.
- He also busted Meteors and travelled all around the galaxy during the entire movie "Ben 10 vs The Universe" through Multiple portals.
That goes to show you not only he defeated "Supergenius Vilgax" and "Stale-mated" Agent Six aka sixth Deadliest Man on Earth but he as well as can One vs 4 People and win, He has enough Experience under his belt.
For reference on how good Vilgax is
Vilgax himself designed the
Omntrix device that transform you into millions of aliens, Conqueror of
10 planets, along with the villain
High Override the destroyer and conqueror of planets who leads his
army to conquer planets, lead to
destruction of his own species planet everyone on Fulmas planet are soldiers with
natural warrior instinct as they are constantly battling with other planets & conquering them, yet
was defeated by Ben as Heatblast and Heatblast has all the resistances mentioned on
Reboot Ben's profile
