Didanewton

Didanewton is Kwan's roommate and Fortune White's manager, who the boys first met in season 1 as an FX IB. His eccentric behaviour and odd fixation with Mario Penis may be a point of contention for some, but the boys accept his various flaws as they usually do with autists. He is also notably one of the first protagonists in the series to awaken the rage of The Mad Biker and stoke the flames of the Puppet Queen's War in season 5.

Awakening The Mad Biker
Although Didanewton is not the first to experience the wrath of The Mad Biker, his actions are critical to the story as his defeat allows the boys to realize something is not quite right. This leads to the investigation which eventually discovers the true villain orchestrating the events of season 5. Didanewton's feud with The Mad Biker will go on to become a consistent rivalry on Summoner's Rift, up to season 6 where Didanewton finally bests The Mad Biker in combat with trusty, rusty Talon jungle.
