Kane-The pyro hits, the light turn red. The pryo hits again, the lights return to normal. Awesome
Cena-May not have any special effects, but his music is so awesome. Plus, he throws his cool hat and shirt to the crowd. His entrance at WM22 was so badass(he shot a gun in an arena).
DX-The music, fireworks and special affects say it all.
The Undertaker-all of his entrances have kicked ass
Johnny Nitro-Can't help but like the camra men and the dance
Edge-awesome music, like how he walks through smoke
The Boogeyman-Red smoke, fire, cool dance. It's awesome
That's all I can come up with right now, but I'll edit my post when I come up with more.
