Roy

"Let's make sure to squish these plumbers so hard, they won't be interfering with us or Father ever again!"

Roy Koopa is one of the Koopalings. Like Morton, he also prefers the mindset of "Brawn over brains", but he doesn't hesitate to think things through before acting, making him more intelligent than Morton. He also acts gruff, and like a tough-guy, even bullies his siblings sometimes, he cannot hurt them, showing that under than hard personality of his, he possesses a heart of gold. He is voiced by Dan Falcone in the saga.

History
Roy first appeared in Super Mario Bros. 3, as the fifth boss, in Sky Land. He later appeared in Super Mario World and NSMB series, after Wii, making him a recurring character.

Lore
Roy Koopa is one of the members of the Koopalings. His first family is unknown, but he was adopted by Bowser at a quite old age, 2 years after Ludwig was adopted. Just like his sibling Morton, he also thinks using brute force is better than brains, but he doesn't hesitate to think before acting, and even saying clever wordplays either.

Just like Morton, Roy was raised to become a leader to Koopa Clan's army, so his strength and brains were tested in all ways, like Morton. Unlike most of his siblings, Roy had different personality traits: He thought he was superior over most, so he would occassionally bully his younger brothers. (Except Morton and Ludwig) But he wouldn't keep this charade long, as he also cared about them beneath, in his heart of gold, taking care of them whenever necessary. He also mainly had a hard shell, acting like a tough guy, and following his fashion around his outer personality.

When he became old enough, Roy was assigned to Sky Land to take control of the kingdom, and he did so, with an iron fist. But that didn't last long, as two heroes ended his reign, like his other siblings. But that didn't stop him from planning to stop his enemies. He tried his best to think of many ways to defeat them: Trying to ram onto them, sneaking from pipes to surprise them and even using a bazooka bill launcher. But as always, he was destined to lose. But he always got up after he fell down, he was determined to beat them someday.

Maybe one day, he'll have an opportunity. He needs to think through more before using full brute force, which he works on improving recently.
