Mark Gabriel G. Javellana,[1] better known by his ring name "The Senyorito" Jake de Leon, is a Filipino professional wrestler most commonly known for his time with Philippine Wrestling Revolution.

[5] In August 2016, PWR held its first ever house show with Asia Pop Comic Convention in which Jake successfully defended his title in three matches throughout the course of the three-day event.

De Leon would lose the title to John Sebastian in the first ever Bacolod Bullrope Match in November at PWR Live: Suplex Sunday.

De Leon would fail to regain the title in a subsequent rematch in January the following year at PWR Live: Bagong Yugto.

[8] At Renaissance, De Leon would face Ralph Imabayashi and defending PWR Champion Chris Panzer in a Triple Threat match,[9] but failed to win the title when De Leon had the Inasal Lock on Imabayashi, allowing Panzer to hit both men with the Eagle Splash and retain the title.

[12] De Leon was one of the participants in the PHX Championship Tournament held during the 2017 Asia Pop Comic Con, where he was eliminated in the first round by Vlad Sinnsyk.

[14] De Leon would make his return two months later at Vendetta as a heel, revealing himself to be John Sebastian's fifth man in a bid to wrestle control of the company from General Manager Sy in an "Ubusan ng Lahi" (5-on-5 elimination) match.

[16] The start of 2018 saw De Leon face Brad Cruz in a winning effort via submission during PWR Live: Kingdome Come.

Later during the event he would attack SANDATA and Dax Xaviera, who were fresh from defeat in their first round match for the Tag Team #1 Contender's Tournament.

Moments after the match, a cryptic video revealed that London Luncha League's Tengu shall face De Leon for the title in PWR: Homefront.

Jake then defended the title in PWR: Vendetta in a Six Pack Elimination Challenge against Warren, Panzer, Crystal, Sebastian and Andreuw "The Statement" Tang.

[48] In July 2020, Jake along with ten other wrestlers and staff filed a joint resignation citing bullying and toxic company culture.

Their departure notably coincided with the suspension of several wrestlers, including fellow departee Chris Panzer, after allegations of sexual harassment in the local wrestling community surfaced in the wake of the #SpeakingOut and #MeToo movements.
