In the world of competitive Super Smash Bros. Melee doubles, there are a few static teams that have gained renown for their powerful coordination: among the most prominent are Zachary “SFAT” Cordoni and Kevin “PewPewU” Toy, Adam “Armada” Lindgren and Andreas “Android” Lindgren, and William “Leffen” Hjelte and Mustafa “Ice” Akcakaya. But last night, viewers who tuned into Smash Studios’ Twitch channel to watch Mexican major Smash Factor 7 were treated to one of the most gripping doubles Top 8s in recent memory—and it was the brotherly pair of Javier “JAVI” Ruiz and Jorge “Twin” Ruiz who unexpectedly stole the show.

Though it’s no surprise that the bonds of brotherhood can elevate teams to greatness—the success of Armada and Android on the world’s biggest stages is all we need to confirm that—JAVI and Twin are identical twins, and their knowledge of each others’ habits is rooted both in nature and in nurture. Though neither the Fox-playing JAVI nor the Falco-maining Twin were ranked on SSBMRank 2017 (JAVI, Mexico’s longtime champion, was a perennial SSBMRank member until inactivity caused him to fall off the list last year), their impressive strategy and unparalleled ability to target switch allowed them to go toe-to-toe with multiple top 100-ranked teams. The Mexican brothers’ synergy was so strong that commentators Pavel “Palco” Guerra and Rodrigo “Roy” Sarmiento dubbed them los hermanos combos—the combo brothers.

“It sounds better in Spanish,” breezed Palco excitedly.
