First things first, welcome to the forum.
I should inform you of some things: By changing Triton's number to #187, he now clashes with those who have Polygone's Star Sapphire mod (http://marvelmods.com/forum/index.php/topic,8934.msg166497.html#msg166497
). Their skins will clash, causing problems. He now also clashes with my mod of Night Thrasher in terms of mannequins. This is why numbers aren't changed, or at the very least a warning is placed for those who download Triton to prevent clashes.
Furthermore, from the looks of Triton's herostat, he's still using Quicksilver's powerstyle, so I highly doubt that both will be successfully playable at the same time. Have you tried using a power as Triton and then as Quicksilver? When you do, you'll notice a clash.
If you wish to change numbers for any character, you have to change quite a few things before it becomes successfully
playable. Refer to this guide for details: http://marvelmods.com/forum/index.php/topic,8737.0.html
. Since you're new, you didn't know, but there is a listing of numbers for every major mod playable in order for modders to keep track and prevent clashes. This is referred to as the CCC, which you will find here: http://marvelmods.com/forum/index.php/topic,9777.0.html
. If you wish to change a mod's number, you should look at the CCC first to see who it will clash with, so you'll know what skin numbers not to use. Then, you have to place a warning to everyone of who it will clash with, so you won't get angry messages from people later on.
