Thanos

Thanos an evil god from Avengers: Infinity War and Endgame. He is the lead supervillain in RS101: The New Academy.

Personality
Although considered by many to be the ultimate embodiment of evil, cruelty and madness, Thanos is in fact a more complicated and tortured soul as he became who he was due to his traumatic past and believed genuinely he was right and his actions of wiping out half of all live would benefit the whole universe. However, Joe Russo noted that his belief is delusional and self-righteous due to the fact that he would force his belief on the whole universe and prove himself right. Thanos proved this by not sparing even the species he had once halved, causing them to become even more less in number. Although not above using the power that the Infinity Stones would grant him, as the Other noted he desired to use the Tesseract to look beyond the known worlds to find greater ones that it would unveil, Thanos didn't take this to extreme levels as he quickly destroyed the Stones after he was done with it and even noted it was to avoid becoming hungry for power. He also didn't appear to care if he were to die as long as he fulfilled his mission.
