Fighter Matchups & Styles
- Lester Martinez: 30 years old (born Oct 17, 1995), 5′ 8″ (173 cm), 71½″ reach, orthodox. Guatemala City resident. Explosive knockout artist (84% KO rate) with heavy hands, body attack, and relentless pressure. Ranked WBC #2–3 and The Ring #4 at super middleweight; coming off a Fight of the Year-level performance. Aims to become Guatemala’s first world/interim champion.
- Immanuwel “The Chosen One” Aleem: 32 years old, 5′ 9″ (175 cm), 70″ reach, orthodox. Richmond, Virginia native. Veteran pressure fighter with solid durability and regional-title experience (WBC FECARBOX, UBO titles). 64% KO rate in wins but has been outpointed or drawn against top competition lately.
Tale of the Tape edge: Martinez in power, youth, ranking, and finishing rate. Aleem in pro experience and veteran savvy, but concedes size and momentum.
Recent Form
Martinez (last 5–6, reverse chronological):
- Sep 2025 – D12 Christian Mbilli (Fight of the Year contender; WBC interim title fight in Las Vegas).
- Mar 2025 – W vs. Joeshon James (San Bernardino).
- Jun 2024 – W vs. Carlos Gongora.
- Feb 2024 – W KO vs. Ruben Angulo (won vacant WBC Latino title).
- Jul 2023 – W vs. Lucas de Abreu.
Martinez is on a 19-fight unbeaten streak (since debut) with 16 stoppages and looked elite in the Mbilli war.
Aleem (last 5–6):
- Jul 2025 – W vs. Demond Nicholson (won vacant UBO Inter-Continental & WBC FECARBOX Light Heavyweight titles).
- Nov 2024 – D vs. Winfred Harris Jr (WBC FECARBOX Super Middleweight).

- Feb 2024 – W vs. Malcolm Jones (won vacant UBO Continental & WBC FECARBOX titles).
- Oct 2023 – W vs. Antonio Louis Hernandez.
Aleem is 4-0-1 in his last five but against regional-level opposition; he stepped up when higher-ranked names declined this title shot.
Fight History Context
Martinez has wins over solid contenders (Gongora, Angulo) and just drew with elite-level Mbilli in a classic. Aleem holds regional belts but has three losses and multiple draws against higher competition. This is Martinez’s first world-title opportunity and Aleem’s biggest step up — a classic “rising star vs. veteran gatekeeper” with massive stakes for the undefeated Guatemalan.
