Is he strong when played well? How does he fair in most match-ups top? Do you like to see him on your team?

Edit: Bonus Question! Toy Soldier or Special Forces?

Only gps i've seen in forever is when i play him :P

He's great... Just make sure to play him utility bank plank

bumpeh

My GF has a Special Forces skin and she does fairly well with him. She's not a fantastic player but she holds her own.

He's a bit underwhelming due to powercreep + some steady nerfs, but he has great utility, scaling, and is possibly one of the best level 1-2 fighters. He's also fairly difficult to gank if experienced and does respectable damage.

Personally, I use Toy Soldier if I will be building more damage and SF GP if I'm going tankier

If he gets fed, does he still become a beast?

"Broken build" GP is one of the more fun champions

Yup. He's not like kat, but he can probably 1v3 and win.

As someone that's faced plenty a fed GP on 3s, he becomes a force, but not in the same sense as Jax, Olaf, Irelia, Riven, Swain, Wukong, Vi, Jayce, Darius when he's fed. GP has to come to a six-item standpoint just to compete with them. He's more of a Pantheon type snowballer, where it's still more than possible to comeback if he's the only one doing well (particularly if he just builds damage). If GP gets ahead, he wants to end it as fast as possible.

If he builds mostly dps than he's pretty squishy and will die to focus (a less farmed/fed Darius, Olaf, Jax... even Sion can still dunk him 1v1 and hard CC/knockups will wreck him in teamfights).

If he builds tanky he doesn't do very much damage (compared to other melees) but has much more survivability, which in this case why not just use someone with more CC and mobility?

Imo his late game scaling isn't too good (no hard CC, true damage, %hp damage, no gap closer, ult stops hurting after a certain point, passive doesn't scale, etc).
