I don't think so. However if someone hosts a server that makes possible to use Lucario Race is free to post information about it here :)

k id be happy seeing a server where we lucario could mingle

I haven't seen a lucario centric server yet honestly. I have seen servers that use the mod in their list, but there are no direct lucario themed servers.

Is one website to find open servers for you to join. There are a few other websites, although personally I do not have good enough internet to host my own server.

Usually I see some mod Devs have a server but I can't supply that unfortunately.
