X-Men: Evolution

When the Brotherhood saves a few people after Wanda accidentally causes a subway accident, they are regarded as heroes. The X-Men are utterly repulsed. The Brotherhood begins to cause accidents just to get famous. When the X-Men figure it out, Pietro tricks Wanda into using her powers to make it look like the X-Men are the villains. After the X-Men are arrested, the Brotherhood tries to cause one last accident. When they can't stop it, the X-Men are released to help. Shadowcat & Jean can't stop the explosion, so Avalanche does. He promises that there will be no more heroics.
