This week’s upcoming War of the Worlds tour is loaded with must-see matches featuring the stars of Ring of Honor and New Japan Pro-Wrestling. Here are five of the most compelling matchups on the tour, which begins in Buffalo, N.Y. (May 8) before heading to Toronto (May 9), Grand Rapids, Mich. (May 11) and Chicago (May 12).

5. WOH WORLD CHAMPION KELLY KLEIN vs. STACY SHADOWS (May 11, Grand Rapids)

Klein and Shadows have met only once before, with Klein winning a hard-fought match in 2017. Shadows, who is in her 10th year as a pro, is one of the few Women of Honor competitors who can match Klein in size and strength. Klein cannot afford to be distracted by her recent run-ins with The Allure (Angelina Love, Velvet Sky and Mandy Leon), or we very well could see a new WOH World Champion crowned in Grand Rapids.

4. BANDIDO vs. FLIP GORDON (May 8, Buffalo)

These fast-rising, young stars were scheduled to square off in January, but the dream match was postponed due to Gordon suffering a knee injury. The last time Bandido and Gordon were in the ring together, it was as tag team partners. They teamed together in the Crockett Cup tournament recently, advancing to the semifinals. There is a mutual respect between Bandido and Gordon, but also a budding rivalry over which of the similarly styled competitors is the better man.

3. JEFF COBB vs. JAY LETHAL vs. PCO vs. RUSH (May 12, Chicago)

Talk about a star-studded match. This Four Corner Survival bout features three competitors who are undefeated in ROH (ROH World Television Champion and NEVER Openweight Champion Cobb, PCO and RUSH) and the record-holder for most combined days as ROH World Champion (Lethal). There’s a chance PCO could enter this match as the new ROH World Champion, which would make the colossal clash even bigger.

2. ROH WORLD TAG TEAM CHAMPIONS G.O.D. vs. JAY AND MARK BRISCOE (May 12, Chicago)

Even if The Guerrillas of Destiny (Tama Tonga and Tanga Loa) lose the ROH World Tag Team Titles to Jay Lethal and Jonathan Gresham on May 8 in Buffalo, the scheduled match between G.O.D. and the Briscoes in Chicago will still take place. Based on how personal the longstanding rivalry between G.O.D. and the Briscoes has become recently, fans can expect an all-out war when the two ultra-violent and highly decorated teams collide.

1. ROH WORLD CHAMPION MATT TAVEN vs. PCO (May 9, Toronto)

PCO has been unbeatable and seemingly indestructible since bursting onto the scene in ROH at the end of 2018. PCO has won more major championships in five months than many competitors will win in their entire careers. The French-Canadian Frankenstein is currently a co-holder of the ROH World Six-Man Tag Team Titles and NWA Tag Team Titles, and he’s a former ROH World Tag Team Champion. Now PCO has his eyes on the richest prize -- the ROH World Championship, which Taven won in a Triple Threat Ladder Match at G1 Supercard in Madison Square Garden on April 6. Eight days later, Taven was pinned by PCO in a six-man tag match at Masters of the Craft in Columbus, Ohio. Will lightning strike again in PCO’s home country?
