might lose followers for this, but it needs to be said: bandit Keith getting his ass kicked in duel by roba
oh boy............ you have no idea how much i’ve thought about this..............
roba and keith dueling in some post-canon tourney overseen by pegasus about a year after battle city, roba has evolved greatly as a duelist & uses the jinzo archetype + generic machine support while keith is still a bit of a scumbag and suffering from all his trauma during the events of canon, uses the barrel dragon archetype with the same machine support as roba
keith knowing juuuust enough about roba to be able to taunt them cruelly about how they cheated in battle city and how it was actually entirely their fault that they lost, because they’re the one who called roulette spider at the wrong time, breaking roba’s spirit and greatly angering any duel spirits that may be watching (*cough* jinzo - lord specifically)
despite this, they continue to duel, keith regularly using his monster’s gambling effects and getting them destroyed in the process and roba angrily states that he doesn’t care for his monsters at all, to which keith smugly replies that yeah, so what? they’re just tools for him to win, so why does it matter? and then jabs them again about how they got their monsters destroyed with roulette spider
this being the last straw for the spirit of jinzo - lord and as keith’s monster attacks them with an open field, he manifests and breaks the rules of the game yugi’s-dark-magician-style to cancel out the attack, much to the surprise of everyone. keith is furious and accuses roba of cheating again, but pegasus, acutely aware of the existence of duel spirits as seen in canon, allows the duel to continue, stating that this was a “fated event” that could not be stopped, being purposefully vague.
roba winning the duel because of this advantage and giving a very pissed off keith a very honest speech about respecting the people, the events, the cards that got him to where he is, and that he’ll perform better that way, and outstretches their hand to him in a very mirroring way to how jounouchi did it to them when they lost!!
tl;dr roba would totally kick keith’s ass in a duel but then also befriend him because they’re just that good of a soul 👏
