- Ben was able to harm Alien X (The strongest enemy Ben has ever faced with reality warping powers)
- Since the user is Ben he was able to defeat Hex who is a 10,000 year old magican with vast knowledgable of dimensional portals 0:18 (who was amplified by dozens of magic books during their battle but Ben outsmarted him multiple times despite his magic amplifications).
- Ben was able to fight against Agent Six who is titled "Sixth deadliest man on the planet" yet Ben was able to hold his own against him during "Ben Gen 10" Crossover
- Here are the Ben vs Vilgax fights and he defeted 4 vs one Weatherheads robots all by himself super casually (Ben vs vilgax, Ben vs Vilgax and Weatherheads and Ben vs Anti-Vilgax who has power 10 different Anti-trix aliens absorbed). Ben is clearly able to keep up with him and robots, monsters from outerspace who are more stronger than him in one vs Multi Opponent scenarios.

Sixth Deadliest Man on Earth but he as well as can One vs 4 People and win, He has enough Experience under his belt.
