True Berserker's True Name is unknown. Its Master, Haruri, comments that it must hate using the power created by his rival, Nikola Tesla, and theorizes that's its reason for going berserk before the Contract was even complete.
Berserker appears as a rust-colored robot with spider-like legs and a lion motif, covered in pistons, wires and cables. Each step it takes produces harsh, mechanical sounds. Incandescent light blazed in its eyes, and the groans that occasionally emanate from it sound distorted, like a record played with a rusty needle. It also appears to possess the capability to change it's appearance, growing large enough to stomp a small prefabricated house flat with ease, sprout cables from its frame to swipe away projectiles, and even visually hide its appearance and sound like optical camouflage.
Berserker's appearance was surprising to Haruri, its summoner, and Faldeus Dioland, who had prepared the catalyst which was used, both of whom knew its identity and expected it to have a more humanoid form. Haruri wondered if the influence of Mazda might have something to do with it.
Not much has been shown of its personality, however, it has been shown to fly into a rage immediately upon summoning, striking down it's Master before a contract could be made. It is also shown to be terrified of Fillia (or rather, the entity possessing her body) who intervenes on Haruri's behalf and forces the contract between the two of them.
Day 0 Edit
On the first day of the war, True Berserker was summoned beneath one of Snowfield's thermal power stations by Haruri Borzak. Immediately after being summoned, it went on a rampage, severely injuring Haruri in the process. Before it could kill her, the possessed Fillia intervened, intimidating True Berserker and making it form a contract with Haruri.
Day 2 Edit
Berserker accompanies Haruri and Fillia when they attack the workshop of Bazdilot Cordelion, the Master of True Archer. Berserker, previously the size of an elephant, becomes large enough that it could wrap its legs around trailers that carry elephants when it appears in the workshop. Berserker easily defends Haruri and Fillia from the Stymphalian Birds summoned by True Archer and the bullet shot by Bazdilot. Berserker then begins to destroy the workshop, and the meat processing plant around it, while also engaging with True Archer. Before their battle can be drawn out, True Caster appears and uses his Noble Phantasm, Grand Illusion, to open a giant hole in the ground where they all fall, by fooling the world itself. While they are falling, Caster manages to make a temporary peace treaty between them, deactivating his Noble Phantasm and return the ground to normal. Berserker, Haruri and Fillia then flee the scene.
Not much has been shown of True Berserker's abilities, however it has been shown to possess abilities of increasing it's size, absorbing rubble, manipulating the cables to attack or defend, uproot and devour electrical cables for a power source to supplement its magical energy, breathing out fire and visually hiding its appearance and sound like optical camouflage. Due to being a Berserker, it lacks proper thinking, acting as a mad beast and even ignoring its own Master.
