Minecraft: Got a Lucas skin online for obvious reasons
Splatoon: I always liked Rollers, but I disliked how they were so slow. The Carbon Roller fixes that; it's very fast and you don't really sacrifice much for it. Burst Bombs give you an instant spot of ink to hide in when the speed of the Carbon Roller isn't enough, and the Inkzooka gives range, which Rollers usually lack. Perfect for my playstyle.
Smash: I main Lucas and second Cloud. I main Lucas because A. He's the main character of Mother 3 (my favorite game of all time) and B. His playstyle works well for me. His playstyle is mostly up close and personal, though he has a fast and powerful projectile to work with. His game mostly focuses on combos and hard reads. Combos are fun to rack up and usually just a better damage dealer than just powerful attacks and no combos. Hard reads are essential to a Lucas player; you'll need it to get off your tether grab; the Rope Snake is your best friend, considering the combo options you can get with him. His Smash attacks are immensely powerful and usually required for him to kill.
Cloud is just plain fun. His Limit Break system works well; at the end of a stock cycle (you deal damage, they deal damage, and you charge limit whenever your opponent isn't pressuring you) and at the perfect time where your opponent is at kill percent you get a powerful Limit Break attack which will finish the job. If you miss your Limit Break, your only option to kill is either play run-away style and get another one, or get a hard read with FSmash, meaning you *have* to land it, and are pressured extremely hard to do so. If you get a hard read with a Limit Break, you can use Finishing Touch to finish the stock extremely early and get a huge lead. Very powerful character. I pull him out as my top tier whenever Lucas gets too difficult to play with.
