"Primo's Plan, Part 3" known as "The Revived Terror, Machine Emperor Wisel" in the Japanese version is the 108th episode of Yu-Gi-Oh! 5D's.
Amidst the chaos in the city, Yusei and Primo duke it out. Primo says that the actions of Yliaster are their "God's Will". Primo who has combined with Terrible Omen, fights in the final evolutionary form of his Duel Runner.
Elsewhere, Lester and Jakob are watching the duel. Lester is still fuming over Yusei receiving a stone tablet - he protests that they are the chosen ones, and Yusei doesn't even know what power the tablets possess. He laments that it's bad enough that Yusei knows that such power exists, but Jakob yells at him to be silent and watch the duel. The duel's outcome will determine if they need to be concerned or not.
Against Primo, Yusei challenges him by Synchro Summoning "Junk Destroyer". Primo laughs and reminds him that his Meklord can abosrb any Synchro Monster that Yusei summons. Yusei decides to act now and get rid of Melord Emperor Wisel while he still has a chance. Yusei uses the effect of "Junk Destroyer" to destroy Primo's set card and "Meklord Emperor Wisel". Primo counters with "Divergence", which redirects the effect of "Junk Destroyer" from "Meklord Emperor Wisel" to "Wisel Carrier". Since the latter can't be destroyed by cards effects, only "Divergence" is destroyed. Yusei then attacks "Meklord Emperor Wisel" with his "Junk Destroyer", but Primo also calls this worthless as he then uses the effect of "Wisel Guard" to redirect the attack to it, destroying it. However Yusei reveals that "Junk Destroyer" can inflict Piercing Damage since "Needle Soldier" was used as a Synchro Material Monster for its Synchro Summon. This angers Primo greatly; he vows to make Yusei pay for doing that.
Primo attempts to absorb "Junk Destroyer" with "Wisel's" effect, but Yusei counters with "Star Shift", which lets him replace "Junk Destroyer" with "Stardust Dragon". Another of his Traps ensures that his new Synchro Monster is safe for a turn while also hitting Primo for even more damage. However, Primo ups the ante by replacing "Wisel Carrier" with "Skiel Carrier 3", which he promptly upgrades to "Skiel Carrier 5". From Yliaster's headquarters, a stunned Lester checks his Deck; he furiously discovers that Primo stole some of his "Skiel" cards for his Duel. Yusei recognizes the new monsters as parts of the Meklord Emperor that Leo and Luna previouslybattled against - he muses that the Duel has become more difficult than ever now that Primo is using "Skiel's" parts to improve "Wisel".
As Primo uses his powered-up "Wisel" to inflict damage to Yusei even through his defenses, the Meklord Emperor's power causes a massive blackout. Jack, Kaz and the others react with confusion; in the hospital, Akiza realizes that Yusei is fighting to save the city.
As the only possible means of opposing the Meklord Emperor, Yusei attempts to perform an Accel Synchro Summon to summon a new card. However, Yusei fails at performing Clear Mind after Primo distracts him by reminding him of the Zero Reverse incident. After easily thwarting Yusei's last desperate attack, Primo has "Wisel" absorb "Stardust Dragon", boosting its ATK to 5000 as it prepares to attack Yusei...
Turn 11: Primo
Primo draws. During the Standby Phase, the effect of "Speed World 2" activates (Primo's SPC: 9 → 10; Yusei's SPC: 5 → 6). Primo then activates the effect of "Meklord Emperor Wisel" to equip itself with "Stardust Dragon" and increase its ATK by the ATK of "Stardust Dragon" ("Meklord Emperor Wisel": 2500 → 5000/0).
"Tech Genus Power Gladiator" attacks directly (Ghost 1000 → 0).
All of the "Skiel" cards that Primo uses in this Duel were stolen from Lester. (He seemingly did this while Lester was next to him during episode 104-105.)
The Comcast/Charter preview for the English dub of this episode says: "Yusei duels Placido, but Placido plans to absorb any monster Yusei summons to help him win.", incorrectly referring to Primo by his Japanese name (Placido).
In the dub, "Quillbolt: Hedgehog is shown as a LIGHT monster instead of EARTH.
In the English dub, when Primo used "Divergence" when Yusei activates "Junk Destroyer's effect", Primo mistakenly explained Divergence's effect as "attack".
In the English dub, the order in which the monsters Yusei was going to use to Synchro Summon do not match the order they appear in. The order they appeared in are "Needle Soldier", "Quillbolt Hedgehog" and "Quickdraw Synchron". Instead, Yusei says he tunes "Quickdraw Synchron", "Needle Soldier" and "Quillbolt Hedgehog".
