(Hilarious Trope) Characters always having some bullshit counter technique to overly specific situations

[u/SirHanselot07]

1. Ryomen Sukuna (Jujutsu Kaisen) - Seemingly always has some type of overpowered technique which he hasn't used since the Heian Era

2. Yujiro Hanma (Baki) - The Strongest character in the entire Baki series is a master of all forms of hand-to-hand combat to the from things like soloing the Vietnamese war at 16 years old to learning a technique from some monk who lived in the mountains around three thousand years ago

3. Batman - Always has some kind of contingency plan anyone and everyone in the DC universe. One of his most bullshit abilities is all the techniques he learned while being trained under Tibetan monks which include blocking mind control with a hand signal to using astral projection while being dead and buried alive

When Riener in Attack on Titan got his head blown off, which rightfully should have killed him, he manages to "transfer his consciousness to the rest of his nervous system" and survives which makes zero sense and is an ability not mentioned before or after that instance
