This may sound stupid but i just thought I'd post this lol. I was sitting here thinking, "What if they made an event, just for like 20 minutes or so, where this huge, tall robot creature walked a city in the game, and players could attack it and such."

Like the citizens of the city are fleeing in fear while all the heroes in the game are attacking it, though I don't think it should do damage to the heroes  because there will probably be low-leveled heroes there too. But it could use some electric attack that halts all of your skills and powers (including travel powers) for 10 seconds.

Just an idea lol. Don't bash me or anything.

Actually, your not far from the mark, there is a Mission at higher levels that will spawn a Giant Titan in Founder's Falls. Missles and lasers and stomping oh my!

Usually it will take 8 people to take it down

Are you aware that most zones have an event like this?

Dark Astoria has Adamastor, a giant Banished Pantheon zombie
Crey's Folly has Jurassik, a giant Devouring Earth monster.
Boomtown has Babbage, a gaint Clockwork monster. (He also spawns in Skyway as part of Positron's Task Force.)
Independence Port has Lusca, a really really giant octopus.
Croatoa has Eochai and Jack in Irons, a pumpkin monster and a giant barbarian who spawn separately and sometimes fight each other.

King's Row has an event where the clockwork all gather to start assembling something. If you don't stop them, they build a large Paladin clockwork monster that roams around. (Though the goal is to stop the construction.)

Talos and IP have a ghost ship that drifts through dropping off spectral ghosts on it's path.
Steel Canyon has buildings that the Hellions light on fire and try to blow up. You have to put out the fires using an extinguisher from the nearby fire chief.
Skyway City has Troll Raves, where they gather to take superdine and become Supa Trolls.

Villain zones have similar events.

Everything I mentioned gives at least one, if not more, badges. There are badge channels on every server specifically to form teams for them. And since issue 12, you can add the "Event Messages" channel to your window to get each of these appearances announced.

Oh cool, I didn't know they had events like that (am not knowledgeable about the events in CoH/CoV) lol. Thanks for the responses guys. =)
