Description
Mechaindojira, built in 974 as an attempt to defend Berk from giant dragons, Mechaindojira first fought Angirasuraus Ⅱ, and.... broke the Dragon's jaw (dont worry, he was perfectly fine a while after) which caused Angirasuraus Ⅱ to retreat, Mechaindojira would later fight Indojira Ⅱ, and after a long intense fight, Mechaindojira was humiliated by Indojira Ⅱ after the Indojira heavily damaged the mecha's jaw (payback, hehe..) at Hunter Island, in 975, Mechaindojira had become a rageful being, still upset and full of hatred towards Indojira Ⅱ after being humiliated in front of humans (even if they were the evil humans), as a result, they teamed up with Titanovenator in an attempt to destroy Indojira Ⅱ, though the battle ended with Titanovenator retreating, and Indojira Ⅱ reasoning with Mechaindojira, as a result, they became allies

(a bit of a more simpler design thankfully, not many line edits with this one)
