The new club-record signing is one of five new additions to the game and can be included in managers' FPL squads for £9.5m.
And he could be a Fantasy gem in his debut season.
The winger enjoyed an outstanding 2018/19 campaign for Lille.
Pepe scored 22 goals and supplied a further 11 assists over his 38 Ligue 1 appearances.
The underlying statistics suggest his all-round contribution can have a major impact on Arsenal.
From his position on the right flank, he averaged a shot every 28.2 minutes last term.
The Ivory Coast international fired 61 shots on target. Among FPL players, only last season's top points scorer, Mohamed Salah (£12.5m), could better that with 64.
Pepe also created 16 big chances, a tally bettered by only two players in FPL and level with Salah.
It is worth bearing in mind, however, that penalties played a big part in Pepe's output.
Nine of his 22 goals came from the spot. But, he won five of those penalties.
Only Wilfried Zaha (£7.0m), with six, won more in FPL in 2018/19.
So even if he does not take them for Arsenal, Pepe's trickery in the opposition box can earn him assists from converted spot-kicks.
Pierre-Emerick Aubameyang (£11.0m) was Arsenal's first-choice penalty-taker last term, scoring four from five.
At a cost of £9.5m, Pepe's potential for both goals and assists is sure to turn the heads of FPL managers.
And his opening run of fixtures could soon make him a must-have midfielder.
In the first 16 Gameweeks, Arsenal face only three of last season's top-six sides.
Marvelous Nakamba (AVL) £4.5m
Joe Willock (ARS) £5.0m
Reiss Nelson (ARS) £5.5m
Arnaut Danjuma (BOU) £6.0m
Nicolas Pepe (ARS) £9.5m
