User blog:Kevo411/OP Nen Abilities?

So I was thinking about it, and most Nen abilities are pretty balanced, with a few exceptions. Mostly because they have certain restrictions on them limiting their usefulness. Take Knov for example. His "Scream" ability can kill anyone, but he has to be in extremely close range in order to use it. And getting that close for Knov is very difficult, making the ability balanced. But many of these restrictions can be worked around by other Nen users. Now continuing with Knov, we know of a certain green Nen user who can get Knov close enough to any opponent without being noticed. By that I mean Meleoron's perfect plan + Knov's scream, I mean they'd be a perfect combo! I'm interested in what abilities or combinations of abilities you think would be overpowered if used correctly. Here are a few of mine:

Meleoron + Baise - Baise could sneak up on anyone without them noticing, use instant lover on them, and they're as good as dead.

Meleoron + Knov - For reasons mentioned above.

Morel + Knuckle - This one isn't overpowered, it's just incredibly well utilized. Considering Knuckle's ability revolves around stalling for time, Morel's ability to hide him, and also make Knuckle lookalikes fits in perfectly.

Shoot + Owl - Owl would create the FunFun Cloth, a piece of cloth that can expand in size, and shrinks anything inside it. Shoot would proceed to grab each end of the cloth with his floating hands and fly them around the opponent, essentially trapping him with no chance to escape. Because let's face it, Shoot's hands are way faster than any opponent.

I could probably think of a few more, but I want to hear what you guys come up with!
