>Kickin' Hawk's only advantages against Rath are martial skills, speed and flexibility and he's smarter.
>Rath's advantage against Kickin' Hawk is physical strength, high jumping and extreme durability, wrestling skills. He is basically Hulk. While he has limited intelligence, he isn't completely stupid but is just brawns-over-brains type of fighter. If he was really stupid, he wouldn't have achieved/completed anything at all; in order to know how to fight and complete missions, you have to have intelligence and Rath doesn't lack it completely. He can be distracted for a moment but that doesn't mean that he will go down so easily due to his stamina and durability.
>As I said, reboot Rath is not afraid of water, Omniverse Rath is afraid of water but we don't know whether AF/UA Rath is or isn't (though aquaphobia for him is logically BS since tigers aren't supposed to fear it but love it). Probably depends on the version, though Kickin' Hawk wouldn't know about that weakness during them fighting.
>Kickin Hawk may able to kick away his opponents via body spin, though the enenies weren't so tough either.
>Rath's anger pro/con depends on the level of its use, it can make him either stronger or it can make him reckless. Provided, he won't let himself lose as his species solely live for wars and fighting.
Ok, let's take a peek at Kickin' Hawk's experience chronicles:
*Rats in "Bros in Space" weren't so tough and big for him to be kicked with no effort though. Rath could do that too since he is also very strong.
*He didn't do much against a physically strong opponent like V.V. Argost and he wasn't fighting him alone, lol.
*He lost to Attea unlike Rath.
*He had a chance to kick Vilgax because Vilgax's hands were tied together, also Vilgax isn't so OP like he used to be in AF/UA.
*He quickly lost to Kevin and they only had a physical combat fight.
*He may have fought the Vreedles by showing his skills and speed but Rath can do the same.
*In "Rook Tales" he quickly lost to that skinny alien dude (he didn't seem so strong but had skills) by having been tricked and then having been kicked into the water.
Kickin' Hawk's kick may be quite impressive enough to kick Charmcaster in her dragon form but Rath has enough strength to lift and throw large stuff with little to no effort. So yea, I don't think Rath would have a hard time against Kickin' Hawk, lol.
