Still needs his ass kicked after more than 20 volumes



Name: Kouichi Hayase
Origin: Kurogane no Linebarrel
Gender: Male
Classification: Factor/Member of the JUDA Organization/Wannabe Hero of Justice/Member of the Katou Corporation (post timeskip)
Age: 14-15, chronologically 17-18 post timeskip
Powers and Abilities: Enhanced physical stats from nanotechnologyregenerationimmortality (type 1), immune to most poisons and diseases, able to summon his mecha anytime | Super strengthspeed, agility and durabilityflight, regeneration (Mid-Low in combat, up to Low-Mid over the time), able to inject people with his nanomachines to resurrect them, has a colossal beam saber | Same but more powerful in addition to teleportation and offensive BFR
Weaknesses: Hotheaded and often reckless. His life depends on the Linebarrel. Destroying it would kill Koichi as well. Overdrive Mode puts a heavy strain on the pilot's body. Using the Executor or teleportation drains the Linebarrel's energy reserves relatively quickly. Oh, did I forget to mention Kouichi is a complete and utter Toolbag?
Destructive Capacity: Wall level | Large Building level+ with physical strikes, at least multi city block level+ w/ the Executor | Multi City block level+ with Executor shots, At least town level+ at full power, possibly higher
Range: Human melee range | Extended mecha melee range, several kilometers with the Executor | Several hundred thousand kilometers 
Speed: Superhuman | Hypersonic+ | Massively Hypersonic 
Durability: Superhuman | Large building level+ (probably higher) | City block level (possibly higher)
Lifting Strength: Superhuman (exact level unknown)  | 100+ tons | 100+ tons (able to throw a warhead to intercept a descending ICBM from several countries away)

Striking Strength: Class KJ | Class MJ+ with physical strikes, Class GJ+ w/ Executor | Class GJ+  with Executor, Class TJ+ at full power, possibly higher
Stamina: Superhuman | Unknown (his machine can operate as long as it has energy reserves left) | Very Large (performed a large scale operation alone where he had to intercept all nuclear missiles in the world)
Standard Equipment: Linebarrel
Intelligence: Skilled combatant but otherwise an average high schooler. He had his brief moments of brilliance, though not enough to overshadow his numerous faults.
Notable Attacks/Techniques:

- Executor: Linebarrel possess a powerful beam weapon hidden inside its tail stabilizer. Initially, Koichi used it as an absurdly strong beam saber with the length ranging from few kilometers to being plain visible in space. Despite its overwhelming power, using Executor was a double - edged sword as it was limited to one or two attacks before running out of power completely. Later Linebarrel got a new flight unit and the Executor was separated from the tail stabilizer. With this "new" Executor Koichi learned to actually shoot beams instead of wasting the energy on the beam saber. The weapon also got a new energy cartridge installed which allows Linebarrel to release many relatively weaker shots or perform the same insane beam saber feat 2-3 times instead of a single use. The beam shots from the new Executor appear to also have the range of many hundred kilometers and are fast enough to casually intercept falling ICBMs from that distance.

- Teleportation/Instant Transmission: The Linebarrel has the ability to teleport over vast distances. Unlike other machinas, its transmission field doesn't require to mark the factor as an exit point. As a result it allows the Linebarrel to teleport over vast distances or even in the middle of combat. Koichi can use the later to avoid otherwise inescapable attacks and appear right behind his enemy for a counter.

- Super-Compressed Transmission Field: Linebarrel's new ability. In Overdrive Mode the palms of the Linebarrel can emit a super-compressed version of the same transmission field that summons the Machinas right next to their Factors. Anything caught inside the field is immediately teleported somewhere else, preferably in many small pieces. Kouichi can also select the objects he wishes to transfer inside the field, effectively disassembling the target. He neutralized an approaching ICBM that way.

- Teleport Warping: Using it super-compressed transmission field the Linebarrel can intercept an opposing attack to warp it to somewhere else. Since the pilot can decided on the teleportation's exit point, it's possible to redirect an attack right back to the sender.
